Set of 7 diamond drill bits for tile and glass [5, 6, 8, 10, 12, 14, 16 mm] with a 6 mm carbide drill bit for hard tiles, ceramic, porcelain stoneware, marble, and granite

Superior Quality: Our diamond drill bits are made of thick, high-quality diamond. Vacuum-brazed diamond technology offers exceptional efficiency, faster cutting, and longer lifespan.

Wet and Dry Drilling Design: These tile drill bits are filled with cooling wax, allowing them to be drilled directly dry without adding water as a coolant.

But to prolong the life of diamond drill bits, it is recommended to add water or other coolant during drilling.

Wide application: This ceramic drill bit is perfect for drilling glass, hard ceramic tiles, porcelain, granite, marble, quartz, limestone, fiberglass, terrazzo, porcelain stoneware, masonry, and sandstone (not for wood).

Unique chip flute and pilot drill design: Our diamond-tipped drill bits are forged and specially designed with chip flutes, also equipped with a pilot drill, allowing them to drill precise and smooth holes in brittle materials such as glass, porcelain, and marble.
